To all whom it may concern:

Be it known that I, GEORGE D. GALLAGHER, a citizen of the United States, residing at New Haven, in the county of New Haven, State of Connecticut, have invented certain new" and useful Improvements in Blade- Sharpening Devices, of which the following is a description, reference being had to the accompanying drawing and to the figures of referenc marked thereonf This invention relates to devices for stropping safety razor blades, and more particuarly to such devices operable by hand.

One of the objects of the present invention is to provide a device of the character- .described'adapted especially for stropping tively interconnected cooperating devices for rotatin said stropping means duringits contact wit the blade.

Another object of this invention consists in providing a device of the character described comprising two relatively reciprocable members including rotatable .stropping means and a blade holder, with devices intermediate said reciprocable members and cooperating therewith so that relative reciprocation of said members automatically rotates said stropping means and also shifts said blade into a position to be sharpened.

Still another ob ect of this invention resides in providing a device of the character described including stropping means and a blade holder, and devices for rotating said stroppin means, first in one direction and then in t e other, and for automatically positioning the blade into engagement with the stropping means, said devices being constructed and arranged so that the pressure of the blade against the 'stropping means may be varied by varying the pressure on the means for rotating the stropping means.

A further feature of this invention con sists in providing a device of the above character includmg two relatively movable meme tive movement of said members, said blade is shifted into contact with the stropping means to thereafter cause the rotation of said stropping means by the relative movement of said members.

Another phase ofthe invention resides in providing a device including a support carrying stropping means and a blade holder, and a member reciprocable'withzrew thereby including means constructed and arranged to move with said member to position the blade to be stropped and to move refiitively to said member to rotate said ro s.

Yet another desirable feature of this in vention resides in providing'a device includ ing a support having-mounted thereon str0p-- ping means and a blade holder, together with spiral means reciprocable relative to said support for rotatin said stropping spect tosaid support and; devices actuated i means and for automatical y positioning the blade with. respect thereto. 5

Another phase of this invention resides in providing a support carrying stropping means and a blade holder, together spiralmeans reciprocable relatively to said a support for rotating the same, and further spiral means for automatically positioning I the. blade with respect to the strapping means. y

These-and other objects will in part be obvious and will'in fully disclosed.

part be; hereinafter more- The invention is shown by way of illus- U tration in Wh.6IGlI1- i A Figure l'is a top plan view of the device; ig. is a side elevation thereof with the the accompanying drawings,

insection;

s end elevation; 4;-1s" a s m'llar new from the othern1ov;ements. --are ,eifect-ed and controlled by a.

simple operation o-tthe hand. (See Figs. 1 and 1 As-frame' =01 basket comprising a metal strip 121-hav1ng angular and relatively parallel,=port-ions 13and 13 is mounted on the pair 'of-spindlesto reciprocate therewith to allow. saidqspindles freedom of rotation. Thedeyice is also provided with stropping mea -.intheipresent instance, consisting of i I I 1 twosliarpening or stropplng rollers 14, each mounted on-one of said spindles within the frame, as shown.

Alsolshiftably arranged on the support or supporting means 8 is a blade holding .means; which in the, presentinstance, is

mounted to oscillate in the frame and consists -bf a split or double slotted tube 15 suitably journaled in the side portions 13 and-13" v of the frame 12, the slots of said tube being adapted to receive a blade B which is held on the blade holding member 16 formed with a pair of studs 17 which engage in the slots or apertures formed in the ordinary bladesof safety razors. The outer-end of theblade holding member 16 is formed with a hand grippingpiece 18 for inserting the blade into the tube 15 by removinglhe same, and for which purpose the end 13 of the. frame and the end 9 of the support are cut away as shown in Figs. 1 and'3.

In lieu of the-blade holder, here shown, any other type of holding device may be employed, 6. g., a suitable piece for holdingthe back of the ordinary razor blade.

The blade holder is adapted to be automatically shifted for alternately presenting the opposite sides of the blade to the strepping means or rolls, and to this end the blade holding member 15 is provided with an extended spiral portion 20 preferably of diiferent pitch from the pitch of the spiral members 23. This spiral portion is preferably relatively flat in cross section and works within the slot 21 formed within the portion 9 of the supporting member 8. It will, therefore be obvious that any rela tlve movement of said support and the frame 12 will impart oscillation to the blade holder. v

In order to operate the device, there is arrange'd a driver or member 22 which re ciprocates relatively to the support 8 and ina plane parallel to the axis of the stropping means carried by said support. This driver or member 22 comprises in its present form, a pair of rods 23 which are formed spirally and pass through the pair of spindles lO'andengage therewith so that the reciprocation of said member 22 will cause the spindles to be simultaneously and uniformly rotated in the same direction. The

engaging elements between the spiral members 23 and the spindles consist of suitable slots or apertures formed in the end portions 11 through which the rods 23 pass, or any other suitably formed devices for accomplishing this purpose may be employed.

The blade holder may be held against accidental displacement during the sharpening operation by means of a device con.- sisting of a disk or plate 24 firmly mounted on one of the spindles 10 by a pair of rings 25. Said disk is disposed slightly diagonally and engages within a notch 26 formed eirculnferentially or partly circumferentially in the blade holder B as shown in Figs. 1 and 7, so that as the disk is ro tated through the spindle on which it is mounted, a slight reciprocatory movement is given the blade holder and blade. This operation assists in the stropping or sharp ening action. The engagement between said member and blade holder is; located at a virtual point which allows the blade to be oscillated without binding or other interference.

Tn the operation of the present device. a

single or double edged blade is inserted in the blade holder after the manner stated and the reciprocable member 22 is given a movement toward the support 8. Due to the fact that the rolls oifer greater resist-- mice against rotation than the blade holder does against shifting, it is evident that when the reciprocable member 22 is moved toward the support 8, the spiral rods 23 instead of immediately rotating the spindles 10 with the rolls thereon, will cause the spindles and the frame carrying the rolls to move -laterally or axially, that is, bodily with the spiral rods, which lateral movement of the frame 12 likewise moves with it axially the spiral. 20, and by reason of its engagement with the slot 21, willctuse the blade holder with its blade to shift or oscillate to present the blade edge properly against the stropping means. The spiral member 20 is preferably given a quicker pitch than the rods 23, as clearly shown in Figs. land 5, so that the blade will be completely shifted into contact with the rolls during the axial displacement of the stropping rolls. The contacting of this blade edge against the stropping means acts as an abutment to prevent further axial movement of the spindles which thus being incapable of'further lateral movement, by reason of the continued movement of the spiral rods 23 and their engagement with the suitable slots formed in the end per-tins 11, rotation will now be imparted to the stropping rolls. This relative rotation between the stropping rolls and the bodily movable spiral rods 23 'is continued ,'until the reciprocable spiral member reaches its innermost position.

tion the same properly against the stropping means. This blade again abutting against the stropping means, prevents further lateral movement of the spindles, the

frame and stropping rolls, so that the spiral.

rods 23 will now cause ,th e stropping rolls to rotateas before, but in a reverse direction.

It must'be also evident that the present device does away with the usual geared conneetion between the hand operated member and the stropping rolls and work holder and 7 the customary friction clutch connection Y against the roll during which permits the blade .to be pressed the rotation of the latter, The present IIIVZGIItlOIl makes use 'of positively inter-connected cooperating devices for. accomplishing this function which connection comprises the: spiral] elements and their cooperating arts.

' It will thus be seen that t e application for positioning of the blade against the roll is under the direct control of the. operator when he applies pressure on the reciprocable member 22, either in its motion toward or away from the support 9.; By

means of this construction, the operator can increase or decrease the pressure of the blade on the stropping surface to provide .a heavy or light stropping effect, as de' sired.

. It is obvious that those skilled in the art may vary the details of construction'and the arrangement of parts .without'departing'from the spirit of my invention, and.

therefore I do not wish to be limited to such features, except as may be required by the claims. 3
